Description

Technical Field

[0001] This utility model relates to the field of magnetic particle inspection auxiliary technology, specifically a rapid drying device for magnetic particle inspection. Background Technology

[0002] Magnetic particle testing is a non-destructive testing method that uses the accumulation of magnetic powder at defects to reveal surface or near-surface defects in a workpiece. During the testing process, a magnetic suspension solution (a mixture of magnetic powder and water or oil) needs to be sprayed onto the workpiece surface. After testing, the workpiece surface needs to be dried to remove residual magnetic suspension solution, facilitating subsequent defect observation and rust prevention treatment.

[0003] Traditional methods of drying using ordinary hot air guns or ovens have significant drawbacks. Uneven distribution of hot air can lead to localized over-drying (causing magnetic powder to clump) or localized under-drying (resulting in residual moisture), affecting the accuracy of flaw detection results.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a rapid drying device for magnetic particle inspection. Utility Model Content

[0005] The purpose of this invention is to provide a rapid drying device for magnetic particle inspection, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid drying device for magnetic particle inspection, comprising a drying chamber and a fixed frame. The drying chamber has a first door and a second door installed sequentially from top to bottom on its exterior. Exhaust vents are provided on both sides of the top of the drying chamber. The fixed frame is positioned between the two sides inside the drying chamber, and a guide groove is provided at the bottom of the fixed frame. A servo motor is located on the lower left side of the drying chamber, and the output end of the servo motor is connected to a bidirectional lead screw. An air inlet pipe is passed through the middle of the fixed frame, and a blower is connected to the input end of the air inlet pipe. A support column is fixed to the other end of the air inlet pipe, and a guide component is fixed to the top of the support column. Bearings are installed in the through holes on both sides of the drying chamber.

[0007] Furthermore, the drying chamber and the fixed frame are integrated into one structure, and the width of the drying chamber is greater than the width of the fixed frame.

[0008] Furthermore, the bidirectional lead screw is transversely inserted into the bearings at the through holes on both sides of the drying chamber, and the fixing frame and the bidirectional lead screw are parallel to each other.

[0009] Furthermore, the external connection of the bidirectional lead screw is a lead screw nut, and a sealing plate is provided at the bottom of the lead screw nut.

[0010] Furthermore, a clamping plate is fixed to the bottom of the sealing plate, and the sealing plate is slidably disposed in the guide groove at the bottom of the fixed frame.

[0011] Furthermore, the clamping plates are symmetrically distributed about the vertical central axis of the bidirectional lead screw, and the fixing frame and the clamping plates are perpendicular to each other.

[0012] Furthermore, the guide element consists of two symmetrical cones, with the tips of the cones facing the air inlet pipe outlet, and the air inlet pipe is located in front of the bidirectional lead screw.

[0013] This invention provides a rapid drying device for magnetic particle inspection, which has the following beneficial effects:

[0014] 1. This utility model starts the blower, allowing external air to be transported through the air inlet pipe to the guide component at the top of the support column. Guided by the guide component, the concentrated airflow is evenly dispersed throughout the entire interior of the drying chamber. Combined with the exhaust vents on both sides of the top to discharge hot and humid air in real time, a highly efficient airflow circulation of air intake, dispersion, drying and exhaust is formed. This process avoids the problems of magnetic powder agglomeration or residual moisture caused by localized airflow concentration in traditional single air ducts, greatly improving the uniformity of workpiece surface drying. Furthermore, due to the improved hot air utilization rate, the drying time of a single workpiece is shortened, thus balancing drying quality and efficiency.

[0015] 2. This utility model uses a servo motor to drive a bidirectional lead screw to rotate, causing the lead screw nut to drive the sealing plate to slide along the guide groove, thereby driving the symmetrically distributed clamping plates to move towards each other and clamp the workpiece. During this process, the sliding cooperation between the sealing plate and the guide groove ensures that the clamping plates move synchronously and smoothly, while tightly blocking the opening of the guide groove, effectively preventing foreign objects such as magnetic powder and dust from entering the fixed frame, avoiding foreign objects from getting stuck or wearing the lead screw nut, and reducing the probability of equipment failure.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, a rapid drying device for magnetic particle inspection includes a drying chamber 1 and a fixed frame 5. The exterior of the drying chamber 1 is equipped with a first door 2 and a second door 3 from top to bottom. Exhaust vents 4 are provided on both sides of the top of the drying chamber 1. The fixed frame 5 is located between the two sides inside the drying chamber 1, and a guide groove 6 is provided at the bottom of the fixed frame 5. The drying chamber 1 and the fixed frame 5 are integrated. The width of the drying chamber 1 is greater than the width of the fixed frame 5. An air inlet pipe 12 is provided through the middle of the fixed frame 5. A blower 15 is connected to the input end of the air inlet pipe 12. A support column 13 is fixed to the other end of the air inlet pipe 12. A guide component 14 is fixed to the top of the support column 13. The guide component 14 is composed of two symmetrical cones with the tips of the cones facing the outlet of the air inlet pipe 12. The air inlet pipe 12 is located in front of the bidirectional lead screw 8.

[0022] The specific operation is as follows: start the blower 15, so that the external air is delivered to the guide 14 at the top of the support column 13 through the air inlet pipe 12. Guided by the guide 14, the concentrated airflow is evenly dispersed to the entire interior of the drying chamber 1. With the exhaust vents 4 on both sides of the top, the hot and humid air is discharged in real time, forming a highly efficient airflow circulation of air inlet, dispersion, drying and exhaust. This process avoids the problem of magnetic powder agglomeration or residual moisture caused by local airflow concentration in traditional single air ducts, which greatly improves the uniformity of workpiece surface drying. Furthermore, due to the improved hot air utilization rate, the drying time of a single workpiece is shortened, thus taking into account both drying quality and efficiency.

[0023] like Figure 2 and Figure 3As shown, a servo motor 7 is installed on the lower left side of the drying chamber 1, and the output end of the servo motor 7 is connected to a bidirectional lead screw 8. Bearings 16 are installed in the through holes on both sides of the drying chamber 1. The bidirectional lead screw 8 is transversely inserted into the bearings 16 in the through holes on both sides of the drying chamber 1. The fixed frame 5 and the bidirectional lead screw 8 are parallel to each other. A lead screw nut 9 is connected to the outside of the bidirectional lead screw 8, and a sealing plate 10 is installed at the bottom of the lead screw nut 9. A clamping plate 11 is fixed at the bottom of the sealing plate 10. The sealing plate 10 is slidably installed in the guide groove 6 at the bottom of the fixed frame 5. The clamping plate 11 is symmetrically distributed about the vertical central axis of the bidirectional lead screw 8, and the fixed frame 5 and the clamping plate 11 are perpendicular to each other.

[0024] The specific operation is as follows: the servo motor 7 drives the bidirectional lead screw 8 to rotate, causing the lead screw nut 9 to drive the sealing plate 10 to slide along the guide groove 6, thereby driving the symmetrically distributed clamping plates 11 to move towards each other and clamp the workpiece. During this process, the sliding cooperation between the sealing plate 10 and the guide groove 6 ensures that the clamping plate 11 moves synchronously and smoothly. At the same time, it tightly blocks the opening of the guide groove 6, effectively preventing foreign objects such as magnetic powder and dust from entering the fixed frame 5, avoiding foreign objects from getting stuck or wearing the lead screw nut 9, and reducing the probability of equipment failure.

[0025] In summary, when using this rapid drying device for magnetic particle inspection, first open the door 2 of the drying chamber 1, place the workpiece after magnetic particle inspection between the two clamping plates 11, and then start the servo motor 7. Its output end drives the two screw nuts 9 on both sides to move towards each other through the bidirectional screw 8. The sealing plate 10 at the bottom of the screw nut 9 slides along the guide groove 6 at the bottom of the fixed frame 5, synchronously driving the symmetrically distributed clamping plates 11 to approach the workpiece until the workpiece is clamped, thus completing the stable clamping of the workpiece and avoiding displacement during the drying process, which would cause uneven hot air coverage.

[0026] Next, close the door 12 and start the blower 15 to deliver external air through the air inlet pipe 12 to the middle of the upper part of the fixed frame 5. When the airflow reaches the guide 14, it is guided by the tip of the cone to evenly disperse the concentrated airflow to the entire interior of the drying chamber 1, avoiding the localized airflow concentration caused by the traditional single air duct.

[0027] The dispersed hot air fully covers the surface of the workpiece, quickly evaporating the moisture in the residual magnetic suspension. At the same time, the exhaust port 4 discharges hot and humid air in real time, forming an airflow cycle of air intake, dispersion, drying and exhaust, which accelerates the removal of moisture. After drying is completed, the blower 15 is turned off, the first door 2 is opened, and the servo motor 7 is started in reverse to release the clamping plate 11, so that the workpiece can be taken out. The second door 3 is located at the bottom, which makes it easy to clean and maintain the lower part of the drying chamber 1.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
